Specification ofLetters Patent.

Patented Dec. 31,1912.

Original application filed November 25, 1910, Serial No. 594,053. Divided and this application filed June 5, 1911. Serial No. 631,272.

To ollwhom "it may concern:

Be it known that 1, Louis BADER, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Means for Feeding Carbid to Acetylene-Gas Generators, of which the following is a specification.

My invention relates to improvements in acetylene gas generators and more especially to means for feeding carbid to said generators, this application being a division of my prior application for improvements in acetylene gas generators filed November 25th, 1910, berial No. 59 1,0553.

The object of the invention is to provide improved feeding means for supplying the carbid to the generator as needed.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification and in which,

Figure 1 is a side elevation of the upper portion of a gas generator embodying my invention, and showing the carbid holder 1n section, Fig. 2, an elevation of the same taken at right angles to the elevation shown in Fig. l and also showing the carbid holder in section, and Fig. 3, an enlarged detail view of the crown gear employed in the device.

The preferred form of construction as illustrated in the drawing comprises a gas generator 1 which may be of any suitable or desired construction. A tank 2 containing a gasometer is mounted upon the top of generator 1 and a discharge pipe 3 also leads from the top of said generator. A gas washing tank 1 is mounted upon the top of pipe 3 and is placed in communication with said pipe by means of a pipe 3'. A pipe 5 leads from the top of the gas cleanser to the bottom of the gasometer 2 as shown. A reciprocating rack bar 6 projects from the top of gasometer 2 and is arranged to be moved upwardly by increase of gas pressure in the gasometer. The specific forms of the cleansing tank and the gasometer constitute the subject matter of my oopending applications and need no furtherillust-ration or description here.

Back bar 6 engages a segmental gear 7 carried by one end of a lever 8 which carries at its other end another segmental gear 9 meshing with a crown gear 10. Crown gear 10'is loosely mounted on a stud shaft 11 and is provided with ratchet teeth 12 in its inner periphery as shown in Fig. 3.

Spring pawls 13 are secured to a disk 14: which in turn is keyed to shaft 11, said ries a sprocket wheel 15 which is connected 1 by means of a sprocket chain 16 with another sprocket wheel 17 carried by the outer end of a shaft 18. Shaft 18 carries a feed wheel 19 which consists of end-disks 20 and partitions 21 arranged between said end disks. At their outer ends partitions 21 are provided with flanges 22 which serve to temporarily retain carbid in the com partments formed by said partitions. Wheel 19 is arranged at the discharge opening of a hopper 23 provided in the carbid holder 24: and is adapted to discharge into a pipe 24 leading to the generator 1. plate 25 is arranged about the upper end of pipe 24: to direct the discharge from wheel 19 into pipe 2 1. A service pipe 26 is connected with gasometer 2 and a glass sight plate 27 is provided in the wall of carbid holder 24: so as to permit a view of the feed ing mechanism.

By the construction above set forth itwill be observed that a decrease of pressure in gasometer 2, causing descent of rack bar 6, will cause rotation of crown gear 10 and shaft 11 thus effecting feed of carbid into generator 1. The'addition of carbid to generator 1 will cause an increase in pressure in the gasometer and thus cause elevation of rack bar 6, which, owing to the operation of the pawls 13 and ratchet teeth 12 will not affect the feed wheel 19. Thus it will be seen that the gas pressure in the gasometer will be maintained practically constant au- A deflector tomatically. The specific construction for elfectingthis result will be found to be eflicient and durable in operation.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification -without departing from the spirit of the invention.

7 I therefore do not wish to be limited to the 1 ing with said rack; a crown gear meshing 'wlth the other segmental gear; and means for converting oscillatory movement of said crown gear int-o continuous movement, substantially asdescribed. I I

2; The combination of a reciprocatory rack; a lever bar pivotally mounted intermediate its ends and having a segmental gear at each end; the gear at one end meshing with said rack; a driven shaft; a crown gear loosely mounted on said shaft and meshing with the other segmental gear; and a pawl and ratchet connection bet-ween said crown gear and said shaft, substantially as described.

3. The combination of a reciprocatory rack; a lever fulorumed intermediate its ends having a segmental gear at each end; the gear at one end meshing with said rack; a driven shaft; a crown gear loosely mounted on said shaft and meshing with the other segmental gear, said crown gear being provided with internal ratchet teeth; a disk having a plurality of recesses in its periphery and arranged within said ratchet teeth; flexible spring pawls in said recesses adapted to engage said ratchet teeth; and an operative connection with said disk, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS BADER.
